Embodiment Construction

[0016] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0017] figure 1 The overall forming mold for concrete stairs shown is used for the construction of pedestrian stairs in a high-rise residential building. It includes upper formwork shell 1, tooth plate 2, pressure bar 3, bolt 4, bottom formwork 5, inner support 6, side plate 7 and guard plate 8. The upper mold shell 1 is the main part in the present invention. In the present embodiment, the upper mold shell 1 is made of a plastic plate, and the mold is a kind of oblique forming mold arranged in order by multiple steps of the same size. In order to reduce the sagging deformation of the upper mold shell 1, the inner support 6 perpendicular to the plane of the bottom mold 5 is arranged at intervals in the lower mold cavity of the upper mold shell 1. Because the present embodiment is a pedestrian staircase in a residential building, the w...

Abstract

The invention discloses an overall concrete stair mold. The overall concrete stair mold comprises an upper mold shell, a toothed board, pressing rods, bolts, a bottom mold, inner supports, a side board and a protection board. The upper mold shell is a multi-step mold made of plastic boards. The inner supports are arranged in mold cavities facing downwards at intervals and are perpendicular to the plane where the bottom mold is located. A material injection opening is formed in the plane of the topmost step. The outer wall of the upper mold shell is reinforced by the fixedly connected toothed plate. When the overall concrete stair mold is installed, the bottom mold and the upper mold shell are erected between a bottom platform and an upper platform together, wherein the upper mold shell is parallel to the bottom mold in a spaced mode, the sides in the width direction are erected close to a wall and the other sides are sealed and blocked through the side board and the protection board, so that the overall stair mold is formed. The overall stair mold is locked by the pressing rods arranged on the toothed plate and the bolts penetrating through the upper mold shell and the bottom mold. The surface of each mold cavity made of the plastic boards is not hydrophilic, so that concrete does not adhere to the surface of each mold cavity and demolding is quite easy. Furthermore, a combined mold structure is adopted, so that installation is easy, detachment is convenient, and reuse is achieved.

Description

technical field [0001] The invention relates to a building construction mold, in particular to a mold for the integral molding of concrete stairs. Background technique [0002] Stairs are the main passage between floors, and there are pedestrian stairs in any building. The traditional pedestrian staircase is a kind of oblique step ladder, which is connected sequentially by a group of right-angle pieces of equal height and width. Because the concrete staircase is a combination of corner fittings, it must be cast in the mold. When multi-storey or high-rise buildings are under construction in contemporary times, the workload for the construction of concrete stairs is very large, and it is necessary to build the staircase formwork in stages as the construction progress of the project. During the construction process, the workers made the stair formwork according to the actual size at the production site without any technical obstacles, and the expected quality could be achieve...
